(Continued from page 28.) 

 [172. Hadena allecto. Smith. — The receipt of specimens of inadata 

 from the east has caused me to doubt the distinctness of allecto.\ 



219. N. haviice, Grt. — I confused this with the foregoing species until 

 quite recently, so cannot state positively whether it is common or not. 

 From memory I should say at least not rare. I picked four out of my 

 series of twenty-five clandestina and sent two to Prof. Smith as possibly 

 havii(Z, but questioned their distinctness. He called them havilcB, and 

 added, " The differences seem obvious enough in my collection. It has 

 the ground colour of primaries lighter, has a peculiar strigate appearance, 

 and lacks all the red-brown that occurs in clandestina^ I much regret 

 having confused the species, and being on that account short of material. 

 My specimens are dated June 16 and July iS. Light. 



220. N. atricmda, Smith. — Described from Calgary. The type is at 

 Washington. A few are taken almost every year at light and treacle, 

 though I have never seen it very common here in the hills. It was com- 

 paratively common near the mouth of Fish Creek (Bow Valley) in 1893, 

 and may be of frequent occurrence there annually. It may be more of a 

 prairie than a hill species, as I found it fairly conmion at treacle on the 

 Red Deer River, about 50 miles north-east of Gleichen, in a strictly open 

 prairie district, in the third week of June, 1901.. End of June and July 

 A very variable species, some specimens being almost immaculate gray 

 and others very strongly marked. A striking feature, and one not men 

 tioned in the description, is that in most specimens, particularly the 9 9 

 the veins on prmiaries are conspicuously pale-lined. The t. a. and t. p, 

 lines are often well marked in blackish, and the orbicular may be quite 

 distinct. Secondaries generally smoky outwardly, occasionally pure 

 pearly white. They sometimes have a smoky transverse central line. 

 The species is figured with the description. 



221. Chorizagrotis auxiliaris, Grt. — June and July. 



222. C. introferens, Grt.— June and July. One specimen, Sept. 9th. 



223. C. agrestis, Grt — June and July. One specimen, May 19th, and 

 another "Circa Sept, 9th." Both dates seem exceptional, 



February, 190^.
